FEEDER-IO E. 'WELLS, OF GREENFIELD, MASSACHUSETTS.

[PAY-WRENCH.

To all whom it may concern:

Be it known that I, Fnnnnnio E. WELLS, a citizen of the United States of America, residing at Greenfield, in the county of Franklin and State of Massachusetts, have invented certain new and useful Improvements in Tap-VVrenches, of which the following is a specification.

This invention relates to a tapwrench for the manipulation of taps or other similar devices, and it is designed particularly to be efficient, simple in operation, and cheap of construction.

Among its most important features, my invention comprises a tapwrench involving a sleeve, two handles and two screws, all assembled in a strong, durable, and mechanically efficient manner.

In the drawings, Figure 1 represents a side elevation of my device; F ig. 2 is a crosssection of the same; and Fig. 3 is a bottom plan View thereof.

The tap-wrench comprises a sleeve a provided with a suitable aperture 6 through which the end of the tap may be passed. Suitably secured in the sleeve (4 is the handle 0 by means of the rivet (Z, or other equivalent device, and provided with, in this instance, the angle-face e. Slidably mounted in the other extremity of the sleeve a is another handle provided with, in this in stance, the double angle-face g and further with a recess it and with the cut-away por- Specification of Letters Patent.

tion 2' forming the shoulder j. The sleeve a carries a screw 7.: which, by engagement with the slot 72, hereinabove described, limits the play of the handle f (see Fig. Q). Mounted in an incline in the sleeve a is a set-screw Z whose square forward end on abuts against the shoulder j upon member hereinabove described. It is obvious that by manipulating the setscrew Z the handle f may be adjusted with relation to the handle 0 to take any size tap or other similar instrument while the screw 70 and slot 7L prevent the device from falling apart unless purposely taken apart.

Having now described my invention, butrecognizing that many changes and modifications may be made from the specific forms in which I have chosen here to illustrate it without departing from the scope of the invention, which is more truly bounded and defined by the claim hereto appended, I claim,-

A tap wrench, comprising, a stock, one of the handles slidable in said stock and formed at their ends to engage the tap, a shoulder on one of said handles, a screw threaded in said stock at an angle to said last named handle and adapted to bear on said shoulder.
